Definitions
- the invention relates to a pipe arrangement for the transport of temperature control medium and a temperature control circuit.
- the invention also relates to a method for producing a pipe arrangement for the transport of temperature control medium.
- Temperature control media are required in electromobility. Batteries in electric vehicles, in particular lithium-ion batteries, have optimum performance only within a limited temperature range. Therefore, depending on the ambient temperature, it may be necessary to heat or cool the batteries. Therefore, the drive unit of an electric vehicle usually has a temperature control circuit with a pipe arrangement through which temperature control media can be passed to the cells of the accumulator in order to control them within a desired temperature range. Due to the limitations of the installation space, the temperature control device should be as compact as possible.
- temperature control components of the entire drive unit of electric vehicles in particular to cool them.
- this includes the power electronics and the electric motor.
- the charging electronics and the associated plug connections and lines can also be cooled by means of the temperature control device. This is particularly relevant in connection with fast charging processes.
- Air conditioning systems in particular mobile air conditioning systems, comprise a pipe arrangement which enables the temperature control medium to be transported between the individual units of the air conditioning system.
- the pipe arrangement is a comparatively complex structure and often comprises pipes made of different materials, for example pipes made of metal, pipe sections made of thermoplastic and pipe sections made of rubber-like material.
- the invention is based on the object of providing a pipe arrangement for the transport of temperature control medium which can be produced simply and inexpensively.
- the pipe arrangement for the transport of temperature control medium comprises a base body made of polymer material by means of blow molding, with at least one functional element being arranged in the base body, which is in operative connection with the temperature control medium.
- Pipe arrangements of temperature control circuits contain several functional elements necessary for the functionality of the air conditioning system. These are, for example, throttle valves, check valves, switchable valves, pumps, flow sensors and temperature sensors.
- the functional elements are in the base body, thus arranged within the pipe arrangement, so that they are in contact with the temperature control medium.
- the pipe arrangement consists of a base body made of polymer material by means of blow molding. Blow molding makes it possible to produce a base body with a complex shape.
- the base body can comprise one or more channels, which can be shaped, for example curved, in the shape required for the installation location. Furthermore, it is particularly easy to shape changes in cross-section into the channels. For example, sections of the channels can be circular, whereas other sections of the channels are not round, for example oval or rectangular.
- the pipe arrangement can be designed to be particularly space-saving and adapted to the installation site. Because the functional elements are integrated directly into the base body, assembly is simple and inexpensive.
- the base body can comprise at least one channel, the at least one functional element being assigned to the channel.
- the functional element is in direct contact with the temperature control medium and can either directly influence the volume flow of the temperature control medium or directly record status data of the temperature control medium, such as temperature, volume flow or pressure.
- the functional element can also be designed as a cooler which is in contact with the temperature control medium and which influences the temperature of the temperature control medium.
- the base body can have a plurality of channels, with a channel wall being able to be located between the channels.
- the base body can accommodate different pipe sections of a temperature control circuit, for example the channel section in front of and behind an evaporator. Both volume flows are separated from one another by the duct wall.
- the pipe arrangement can also function as a distributor and / or connector.
- At least one functional element can be formed from the base body.
- the functional element can form a throttle valve.
- a throttle valve or expansion valve causes a local narrowing of the flow cross-section to reduce the pressure of the temperature control medium flowing through and at the same time causes the temperature control medium to expand.
- the throttle valve is designed as an unregulated throttle valve and forms a constriction of the channel. Because the throttle valve is formed directly from the base body, the pipe arrangement can be manufactured particularly inexpensively and easily.
- the functional element can also be designed as a fluid distribution element. It is also conceivable that the functional element is designed as a connecting element or connector. As a result, the pipe arrangement can be equipped to be connected to other components of a temperature control circuit.
- At least one functional element can be formed separately from the base body.
- Functional elements which have components made of non-thermoplastic material and / or can be actively controlled are preferably formed separately from the base body.
- Such functional elements are, for example, throttle valves made of metallic material, switchable valves, check valves with metallic spring bodies, sensors, for example temperature sensors, pressure sensors or flow sensors, pumps, connecting elements or connectors for connecting the pipe arrangement to units or the like.
- the separately designed functional elements are arranged within the base body.
- the base body in turn consists of a base body made of polymeric material produced by means of blow molding, which is made of a single material and is made in one piece.
- the separately formed functional elements are placed in the interior of the blank forming the base body before the base body is formed in the blow molding process. After shaping by means of blow molding, the fluidic functional elements are arranged in a stationary manner in the base body. This enables the production of a functional pipe arrangement with complex geometry with simple process steps.
- the pipe arrangement forms part of a temperature control circuit.
- the pipe arrangement is part of an air conditioning circuit of an air conditioning system.
- the air conditioning system can in particular be designed as a mobile air conditioning system.
- the mobile air conditioning system in turn, can be part of a motor vehicle, the air conditioning system being used for air conditioning the vehicle interior.
- the base body of the pipe arrangement may have a complex geometry and can contain several fluidic functional elements, the pipe arrangement is nevertheless easy to assemble and has only a few parts.
- the pipe arrangement according to the invention simplifies the complexity, in particular, of a mobile air conditioning system in a motor vehicle. This is particularly advantageous with regard to electrically driven motor vehicles, since these only have a very limited installation space due to the accumulator required for the electric drive.
- the blow molding process makes it possible for the pipe arrangement to be adapted to the available installation space, the channels for the transport of temperature control medium being dimensioned in such a way that optimal transport of temperature control medium is possible.
- the pipe arrangement is part of a temperature control circuit of the drive unit of an electric vehicle.
- the pipe arrangement supplies temperature control medium to the elements of the drive unit to be temperature-controlled, so that the elements can be temperature-controlled within a desired temperature spectrum.
- the accumulators can be heated or cooled depending on the requirements.
- components of the power electronics and also plug connections can be cooled by means of a temperature control medium.
- the cooling of plug connections is particularly advantageous in fast charging processes, since during fast charging the plug connections can become very hot due to the high charging currents. Because the tube assembly is blow molded, the tube assembly can be manufactured in a wide variety of shapes. This is particularly advantageous with regard to the limited and complexly shaped installation space of the aforementioned components for a pipe arrangement.
- a preform made of polymeric material is provided, the preform being arranged in a blow mold and the pipe arrangement being shaped by means of a blow molding process, the blow mold being designed in such a way that at least one fluidic functional element is molded into the pipe arrangement.
- the method according to the invention is particularly suitable for providing a pipe arrangement for the air conditioning circuit of an air conditioning system, the fluidic functional element being designed as a throttle valve which is molded directly into a channel of the pipe arrangement.
- a preform made of polymeric material and at least one functional element to be arranged inside the pipe arrangement are provided, the at least one functional element being arranged inside the preform, the The preform with the at least one functional elements arranged therein is arranged in a blow mold and the tube arrangement is shaped by means of a blow molding process. Accordingly, the functional element is arranged in the base body before it is given its final shape in the blow molding process. Due to the plastic deformation of the material of the base body, the functional elements can be firmly embedded in the interior of the base body. As a result, the elements are placed in the base body in a captive and stationary manner. The fact that the functional elements are integrated directly into the base body makes the assembly of the pipe arrangement easier. Furthermore, due to the arrangement inside the pipe arrangement, the functional elements are directly in operative connection with the temperature control medium.
- a first functional element is molded directly into the base body during the blow molding process, while a second functional element is arranged in the interior of the preform before molding and is given its place after the blow molding process has been completed.
- the two processes mentioned above are combined. This makes it possible, for example, to form a throttle valve in a channel of the pipe arrangement during the blow molding process and to place further functional elements such as check valves, sensors, pumps or connection blocks in the base body.
- Figure 1 shows a pipe arrangement 1 for the transport of temperature control medium, comprising a base body 2 made of polymer material, which is produced by means of blow molding. At least one functional element 3, which is in operative connection with the temperature control medium, is arranged in the base body 2. The functional element 3 is arranged in a channel 4, the functional element 3 being formed in one piece from the base body 2. The functional element 3 forms a throttle valve and is formed by a cross-sectional constriction of the channel 4.
- Figure 2 shows a pipe arrangement 1 according to Figure 1 , wherein the base body 2 comprises a plurality of functional elements 3, which are formed separately from the base body 2 and are arranged in the interior of the base body 2.
- the base body 2 has a plurality of channels 4, a channel wall 5 being located between each of the channels 4.
- the pipe arrangement 1 comprises several functional elements 3, including a check valve 3 ', a temperature sensor, a pressure sensor, a flow sensor and a connector in the form of a connection block 3 ′′ for connecting the pipe arrangement 1 to adjacent units or pipelines Throttle valve 3 ′ ′′ which is molded directly into a channel 4 and which is molded from the base body 2 from the same material and in one piece.
- Figure 3 shows an alternative embodiment of the in Figure 2 1.
- Several functional elements 3 in the form of a check valve 3 'and several connectors 3 ′′ ′′ are introduced into the tube arrangement 1.
- the pipe arrangements 1 shown form part of an air conditioning circuit of an air conditioning system, the air conditioning system being designed as a mobile air conditioning system of a motor vehicle.
- the pipe arrangements 1 form part of a temperature control circuit of the drive unit of an electric vehicle, the pipe arrangements 1 supplying temperature control medium to the cells of the accumulators and the electrical control components and plug connections.
- the pipe arrangement 1 is part of a temperature control device which is set up to control the temperature of components of the drive unit of electric vehicles.
- this includes the power electronics and the electric motors.
- the temperature control device is set up to cool the charging electronics and the associated plug connections and lines, which is particularly advantageous in connection with fast charging processes.
- the temperature control device can be set up to control the temperature of components of the remaining vehicle electronics, in particular to cool them.
- Such components are, for example, sensors and computers for autonomous driving and on-board computers.
- a preform made of polymeric material is provided, the preform being arranged in a blow mold and the tube arrangement 1 being shaped by means of a blow molding process.
- the blow mold is designed in such a way that the functional element 3 is molded into the pipe arrangement 1.
- a preform consisting of polymeric material at least one functional element 3 to be arranged inside the pipe arrangement 1 is provided, the at least one functional element 3 being arranged in the interior of the preform, the preform with the at least one functional element 3 arranged therein being arranged in a blow mold and the pipe arrangement 1 is formed by means of a blow molding process.

Description
Die Erfindung betrifft eine Rohranordnung für den Transport von Temperiermedium sowie einen Temperierkreislauf. Die Erfindung betrifft ferner ein Verfahren zur Herstellung einer Rohranordnung für den Transport von Temperiermedium.The invention relates to a pipe arrangement for the transport of temperature control medium and a temperature control circuit. The invention also relates to a method for producing a pipe arrangement for the transport of temperature control medium.
Temperiermedien werden in der Elektromobilität benötigt. Akkumulatoren von Elektrofahrzeugen, insbesondere Lithium-Ionen-Akkumulatoren weisen eine optimale Leistungsfähigkeit nur innerhalb eines begrenzten Temperaturspektrums auf. Daher kann es je nach Umgebungstemperatur erforderlich sein, die Akkumulatoren zu erwärmen oder zu kühlen. Daher weist die Antriebseinheit eines Elektrofahrzeugs in der Regel einen Temperierkreislauf mit einer Rohranordnung auf, durch welchen Temperiermedien zu den Zellen des Akkumulators geleitet werden können, um diese innerhalb eines gewünschten Temperaturspektrums zu temperieren. Aufgrund der Beschränkungen des Bauraums soll die Temperiereinrichtung dabei möglichst kompakt sein.Temperature control media are required in electromobility. Batteries in electric vehicles, in particular lithium-ion batteries, have optimum performance only within a limited temperature range. Therefore, depending on the ambient temperature, it may be necessary to heat or cool the batteries. Therefore, the drive unit of an electric vehicle usually has a temperature control circuit with a pipe arrangement through which temperature control media can be passed to the cells of the accumulator in order to control them within a desired temperature range. Due to the limitations of the installation space, the temperature control device should be as compact as possible.
Des Weiteren kann es erforderlich sein, Komponenten der gesamten Antriebseinheit von Elektrofahrzeugen zu temperieren, insbesondere zu kühlen. Hierzu gehören neben dem Akkumulator die Leistungselektronik und der Elektromotor. Die Ladeelektronik und die dazugehörigen Steckverbindungen und Leitungen können ebenfalls mittels der Temperiereinrichtung gekühlt werden. Dies ist insbesondere im Zusammenhang mit Schnellladevorgängen relevant.Furthermore, it may be necessary to temperature control components of the entire drive unit of electric vehicles, in particular to cool them. In addition to the accumulator, this includes the power electronics and the electric motor. The charging electronics and the associated plug connections and lines can also be cooled by means of the temperature control device. This is particularly relevant in connection with fast charging processes.
Neben dem Einsatz in einer Antriebseinheit ergibt sich ein weiteres Einsatzgebiet im Zusammenhang mit der übrigen Fahrzeugelektronik, hier insbesondere von Sensoren und Bordcomputern. Ist ein Fahrzeug zum Autonomen Fahren ausgerüstet, werden leistungsfähige Sensoren und leistungsfähige Rechner benötigt, wobei die System redundant vorhanden sind. Dadurch, dass der Bauraum beschränkt ist, ergibt sich auch bei diesen System ein Bedarf zur Temperierung/Kühlung durch eine Temperiereinrichtung.In addition to the use in a drive unit, there is another area of application in connection with the rest of the vehicle electronics, in particular sensors and on-board computers. If a vehicle is equipped for autonomous driving, powerful sensors and powerful computers are required, and the systems are redundant. Because the installation space is limited, there is also a need for temperature control / cooling by a temperature control device in this system.
Temperiermedien kommen ferner in Klimaanlagen zum Einsatz. Klimaanlagen, insbesondere mobile Klimaanlagen, umfassen eine Rohranordnung, welche den Transport von Temperiermedium zwischen den einzelnen Aggregaten der Klimaanlage ermöglicht. Bei mobilen Klimaanlagen, beispielsweise bei Klimaanlagen für die Klimatisierung von Innenräumen von Kraftfahrzeugen, ist die Rohranordnung ein vergleichsweise komplexes Gebilde und umfasst häufig Rohre aus verschiedenen Materialien, beispielsweise Rohre aus Metall, Rohrabschnitte aus thermoplastischem Kunststoff und Rohrabschnitte aus gummiartigem Material. Zwar können hierbei die Einsatzbedingungen der Rohrabschnitte optimal auf die jeweiligen Anforderungen abgestimmt werden, die Rohranordnung ist jedoch kostenintensiv, aufwendig in der Montage und schwierig zu recyceln.Temperature control media are also used in air conditioning systems. Air conditioning systems, in particular mobile air conditioning systems, comprise a pipe arrangement which enables the temperature control medium to be transported between the individual units of the air conditioning system. In mobile air conditioning systems, for example air conditioning systems for air conditioning the interiors of motor vehicles, the pipe arrangement is a comparatively complex structure and often comprises pipes made of different materials, for example pipes made of metal, pipe sections made of thermoplastic and pipe sections made of rubber-like material. Although the conditions of use of the pipe sections can be optimally matched to the respective requirements, the pipe arrangement is cost-intensive, complex to assemble and difficult to recycle.
Der Erfindung liegt die Aufgabe zugrunde, eine Rohranordnung für den Transport von Temperiermedium bereitzustellen, welche einfach und kostengünstig herstellbar ist.The invention is based on the object of providing a pipe arrangement for the transport of temperature control medium which can be produced simply and inexpensively.
Diese Aufgabe wird mit den Merkmalen der Ansprüche 1, 8, 10 und 11 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die jeweils darauf rückbezogenen Unteransprüche Bezug.This object is achieved with the features of
Zur Lösung der Aufgabe umfasst die Rohranordnung für den Transport von Temperiermedium einen mittels Blasformen hergestellten Grundkörper aus polymerem Werkstoff, wobei in dem Grundkörper zumindest ein Funktionselement angeordnet ist, welches mit dem Temperiermedium in Wirkverbindung steht.To achieve the object, the pipe arrangement for the transport of temperature control medium comprises a base body made of polymer material by means of blow molding, with at least one functional element being arranged in the base body, which is in operative connection with the temperature control medium.
Rohranordnungen von Temperierkreisläufen enthalten mehrere für die Funktionsfähigkeit der Klimaanlage erforderliche Funktionselemente. Dies sind beispielsweise Drosselventile, Rückschlagventile, schaltbare Ventile, Pumpen, Durchflusssensoren und Temperatursensoren. Bei der erfindungsgemäßen Rohranordnung sind zumindest einige der Funktionselemente in dem Grundkörper, also innerhalb der Rohranordnung, angeordnet, so dass diese mit dem Temperiermedium in Kontakt stehen.Pipe arrangements of temperature control circuits contain several functional elements necessary for the functionality of the air conditioning system. These are, for example, throttle valves, check valves, switchable valves, pumps, flow sensors and temperature sensors. In the pipe arrangement according to the invention, at least some of the functional elements are in the base body, thus arranged within the pipe arrangement, so that they are in contact with the temperature control medium.
Die Rohranordnung besteht aus einem mittels Blasformen hergestellten Grundkörper aus polymerem Material. Durch das Blasformen ist es möglich, einen Grundkörper mit einer komplexen Gestalt herzustellen. Beispielsweise kann der Grundkörper einen oder mehrere Kanäle umfassen, welche in der für den Montageort erforderlichen Gestalt geformt, beispielsweise gekrümmt, sein können. Des Weiteren ist es besonders einfach, Querschnittsänderungen in die Kanäle einzuformen. Beispielsweise können Abschnitte der Kanäle kreisförmig sein, wohingegen andere Abschnitte der Kanäle nicht rund, beispielsweise oval oder rechteckig, ausgebildet sind. Dadurch kann die Rohranordnung besonders platzsparend ausgebildet und an den Montageort angepasst sein. Dadurch, dass die Funktionselemente direkt in den Grundkörper integriert sind, ist die Montage einfach und kostengünstig.The pipe arrangement consists of a base body made of polymer material by means of blow molding. Blow molding makes it possible to produce a base body with a complex shape. For example, the base body can comprise one or more channels, which can be shaped, for example curved, in the shape required for the installation location. Furthermore, it is particularly easy to shape changes in cross-section into the channels. For example, sections of the channels can be circular, whereas other sections of the channels are not round, for example oval or rectangular. As a result, the pipe arrangement can be designed to be particularly space-saving and adapted to the installation site. Because the functional elements are integrated directly into the base body, assembly is simple and inexpensive.
Der Grundkörper kann zumindest einen Kanal umfassen, wobei das zumindest eine Funktionselement dem Kanal zugeordnet ist. Dadurch steht das Funktionselement in unmittelbarem Kontakt mit dem Temperiermedium und kann entweder direkt den Volumenstrom des Temperiermediums beeinflussen oder direkt Zustandsdaten des Temperiermediums, wie Temperatur, Volumenstrom oder Druck, erfassen. Das Funktionselement kann auch als Kühler ausgebildet sein, welches in Kontakt mit dem Temperiermedium steht und welches die Temperatur des Temperiermediums beeinflusst.The base body can comprise at least one channel, the at least one functional element being assigned to the channel. As a result, the functional element is in direct contact with the temperature control medium and can either directly influence the volume flow of the temperature control medium or directly record status data of the temperature control medium, such as temperature, volume flow or pressure. The functional element can also be designed as a cooler which is in contact with the temperature control medium and which influences the temperature of the temperature control medium.
Der Grundkörper kann mehrere Kanäle aufweisen, wobei sich zwischen den Kanälen eine Kanalwand befinden kann. Dadurch kann der Grundkörper verschiedene Rohrabschnitte eines Temperierkreislaufs aufnehmen, beispielsweise den Kanalabschnitt vor und hinter einem Verdampfer. Durch die Kanalwand sind beide Volumenströme voneinander getrennt.The base body can have a plurality of channels, with a channel wall being able to be located between the channels. As a result, the base body can accommodate different pipe sections of a temperature control circuit, for example the channel section in front of and behind an evaporator. Both volume flows are separated from one another by the duct wall.
Je nach Anzahl und Ausgestaltung der Kanäle kann die Rohranordnung auch als Verteiler und/oder Konnektor fungieren.Depending on the number and configuration of the channels, the pipe arrangement can also function as a distributor and / or connector.
Zumindest ein Funktionselement kann aus dem Grundkörper ausgeformt sein. Dies ist insbesondere dann denkbar, wenn das Funktionselement ein passives Funktionselement ist und keinerlei bewegliche Teile aufweist. Beispielsweise kann das Funktionselement ein Drosselventil bilden. Ein Drosselventil, beziehungsweise Expansionsventil, bewirkt durch eine lokale Verengung des Strömungsquerschnitts eine Verminderung des Drucks des durchfließenden Temperiermediums und bewirkt gleichzeitig eine Expansion des Temperiermediums. Das Drosselventil ist dabei als ungeregeltes Drosselventil ausgebildet und bildet eine Einschnürung des Kanals. Dadurch, dass das Drosselventil direkt aus dem Grundkörper ausgeformt ist, ist die Rohranordnung besonders kostengünstig und einfach herstellbar. Das Funktionselement kann auch als Fluidverteilungselement ausgebildet sein. Ferner ist denkbar, dass das Funktionselement als Verbindungselement oder Konnektor ausgebildet ist. Dadurch kann die Rohranordnung ausgerüstet sein, mit weiteren Komponenten eines Temperierkreislaufs verbunden zu werden.At least one functional element can be formed from the base body. This is particularly conceivable when the functional element is a passive functional element and has no moving parts. For example, the functional element can form a throttle valve. A throttle valve or expansion valve causes a local narrowing of the flow cross-section to reduce the pressure of the temperature control medium flowing through and at the same time causes the temperature control medium to expand. The throttle valve is designed as an unregulated throttle valve and forms a constriction of the channel. Because the throttle valve is formed directly from the base body, the pipe arrangement can be manufactured particularly inexpensively and easily. The functional element can also be designed as a fluid distribution element. It is also conceivable that the functional element is designed as a connecting element or connector. As a result, the pipe arrangement can be equipped to be connected to other components of a temperature control circuit.
Zumindest ein Funktionselement kann separat von dem Grundkörper ausgebildet sein. Vorzugsweise sind von dem Grundkörper separat Funktionselemente ausgebildet, welche Komponenten aus nicht-thermoplastischem Material aufweisen und/oder aktiv steuerbar sind. Derartige Funktionselemente sind beispielsweise Drosselventile aus metallischem Material, schaltbare Ventile, Rückschlagventile mit metallischem Federkörper, Sensoren, beispielsweise Temperatursensoren, Drucksensoren oder Durchflusssensoren, Pumpen, Verbindungselemente oder Konnektoren zum Verbinden der Rohranordnung mit Aggregaten oder dergleichen. Dabei sind die separat ausgebildeten Funktionselemente innerhalb des Grundkörpers angeordnet. Der Grundkörper wiederum besteht aus einem mittels Blasformen hergestellten Grundkörper aus polymerem Werkstoff, welcher materialeinheitlich und einstückig ausgebildet ist. Die separat ausgebildeten Funktionselemente sind dabei vor dem Ausformen des Grundkörpers im Blasformverfahren im Inneren des den Grundkörper bildenden Rohlings plaziert. Nach dem Ausformen mittels Blasformen sind die strömungstechnischen Funktionselemente ortsfest in dem Grundkörper angeordnet. Dadurch ist die Herstellung einer funktionalen Rohranordnung mit komplexer Geometrie mit einfachen Verfahrensschritten möglich.At least one functional element can be formed separately from the base body. Functional elements which have components made of non-thermoplastic material and / or can be actively controlled are preferably formed separately from the base body. Such functional elements are, for example, throttle valves made of metallic material, switchable valves, check valves with metallic spring bodies, sensors, for example temperature sensors, pressure sensors or flow sensors, pumps, connecting elements or connectors for connecting the pipe arrangement to units or the like. The separately designed functional elements are arranged within the base body. The base body in turn consists of a base body made of polymeric material produced by means of blow molding, which is made of a single material and is made in one piece. The separately formed functional elements are placed in the interior of the blank forming the base body before the base body is formed in the blow molding process. After shaping by means of blow molding, the fluidic functional elements are arranged in a stationary manner in the base body. This enables the production of a functional pipe arrangement with complex geometry with simple process steps.
In einer erfindungsgemäßen Verwendung bildet die Rohranordnung einen Teil eines Temperierkreislaufs.In a use according to the invention, the pipe arrangement forms part of a temperature control circuit.
Gemäß einer ersten Ausgestaltung ist die Rohranordnung Teil eines Klimakreislaufs einer Klimaanlage. Dabei kann die Klimaanlage insbesondere als mobile Klimaanlage ausgebildet sein. Die mobile Klimaanlage wiederum kann Bestandteil eines Kraftfahrzeugs sein, wobei die Klimaanlage der Klimatisierung des Fahrzeuginnenraums dient. Dadurch, dass der Grundkörper der Rohranordnung zwar eine komplexe Geometrie aufweisen und mehrere strömungstechnische Funktionselemente beinhalten kann, ist die Rohranordnung dennoch einfach zu montieren und weist nur wenige Teile auf. Insofern vereinfacht die erfindungsgemäße Rohranordnung die Komplexität insbesondere einer mobilen Klimaanlage eines Kraftfahrzeugs. Dies ist insbesondere in Bezug auf elektrisch angetriebene Kraftfahrzeuge vorteilhaft, da diese aufgrund des für den Elektroantrieb erforderlichen Akkumulators nur über einen sehr beschränkten Bauraum verfügen. Das Blasformverfahren ermöglicht es, dass die Rohranordnung an den zur Verfügung stehenden Bauraum angepasst ist, wobei die Kanäle für den Transport von Temperiermedium so bemessen sind, dass ein optimaler Transport von Temperiermedium möglich ist.According to a first embodiment, the pipe arrangement is part of an air conditioning circuit of an air conditioning system. The air conditioning system can in particular be designed as a mobile air conditioning system. The mobile air conditioning system, in turn, can be part of a motor vehicle, the air conditioning system being used for air conditioning the vehicle interior. Because the base body of the pipe arrangement may have a complex geometry and can contain several fluidic functional elements, the pipe arrangement is nevertheless easy to assemble and has only a few parts. To this extent, the pipe arrangement according to the invention simplifies the complexity, in particular, of a mobile air conditioning system in a motor vehicle. This is particularly advantageous with regard to electrically driven motor vehicles, since these only have a very limited installation space due to the accumulator required for the electric drive. The blow molding process makes it possible for the pipe arrangement to be adapted to the available installation space, the channels for the transport of temperature control medium being dimensioned in such a way that optimal transport of temperature control medium is possible.
Gemäß einer zweiten Ausgestaltung ist die Rohranordnung Teil eines Temperierkreislaufs der Antriebseinheit eines Elektrofahrzeugs. Dabei führt die Rohranordnung den zu temperierenden Elementen der Antriebseinheit Temperiermedium zu, so dass die Elemente innerhalb eines gewünschten Temperaturspektrums temperiert werden können. Beispielsweise können die Akkumulatoren je nach Anforderung erwärmt oder gekühlt werden. Des Weiteren können Komponenten der Leistungselektronik und auch Steckverbindungen mittels Temperiermedium gekühlt werden. Die Kühlung von Steckverbindungen ist dabei insbesondere bei Schnellladevorgängen vorteilhaft, da beim Schnellladen aufgrund der hohen Ladeströme starke Erwärmungen an Steckverbindungen auftreten können. Dadurch, dass die Rohranordnung im Blasformen geformt ist, kann die Rohranordnung in einer großen Formenvielfalt hergestellt werden. Dies ist insbesondere im Hinblick auf den für eine Rohranordnung beschränkten und komplex geformten Bauraum der zuvor genannten Komponenten vorteilhaft.According to a second embodiment, the pipe arrangement is part of a temperature control circuit of the drive unit of an electric vehicle. The pipe arrangement supplies temperature control medium to the elements of the drive unit to be temperature-controlled, so that the elements can be temperature-controlled within a desired temperature spectrum. For example, the accumulators can be heated or cooled depending on the requirements. Furthermore, components of the power electronics and also plug connections can be cooled by means of a temperature control medium. The cooling of plug connections is particularly advantageous in fast charging processes, since during fast charging the plug connections can become very hot due to the high charging currents. Because the tube assembly is blow molded, the tube assembly can be manufactured in a wide variety of shapes. This is particularly advantageous with regard to the limited and complexly shaped installation space of the aforementioned components for a pipe arrangement.
Bei einem erfindungsgemäßen Verfahren zur Herstellung einer Rohranordnung für den Transport von Temperiermedium gemäß einer ersten Ausgestaltung wird ein aus polymerem Material bestehender Vorformling bereitgestellt, wobei der Vorformling in einer Blasform angeordnet wird und die Rohranordnung mittels Blasformverfahren ausgeformt wird, wobei die Blasform derart ausgebildet ist, dass in die Rohranordnung zumindest ein strömungstechnisches Funktionselement eingeformt wird. Das erfindungsgemäße Verfahren eignet sich insbesondere dazu, eine Rohranordnung für den Klimakreislauf einer Klimaanlage bereitzustellen, wobei das strömungstechnische Funktionselement als Drosselventil ausgebildet ist, welches direkt in einen Kanal der Rohranordnung eingeformt wird.In a method according to the invention for producing a pipe arrangement for the transport of temperature control medium according to a first embodiment, a preform made of polymeric material is provided, the preform being arranged in a blow mold and the pipe arrangement being shaped by means of a blow molding process, the blow mold being designed in such a way that at least one fluidic functional element is molded into the pipe arrangement. The method according to the invention is particularly suitable for providing a pipe arrangement for the air conditioning circuit of an air conditioning system, the fluidic functional element being designed as a throttle valve which is molded directly into a channel of the pipe arrangement.
Bei einem erfindungsgemäßen Verfahren zur Herstellung einer Rohranordnung für den Transport von Temperiermedium gemäß einer zweiten Ausgestaltung wird zunächst ein aus polymerem Material bestehender Vorformling und zumindest ein im Inneren der Rohranordnung anzuordnendes Funktionselement bereitgestellt, wobei das zumindest eine Funktionselement im Inneren des Vorformlings angeordnet wird, wobei der Vorformling mit den darin angeordneten, zumindest einem, Funktionselementen in einer Blasform angeordnet wird und die Rohranordnung mittels eines Blasformverfahrens ausgeformt wird. Dementsprechend wird das Funktionselement in dem Grundkörper angeordnet, bevor dieser im Blasformverfahren seine endgültige Form erhält. Aufgrund des plastischen Verformens des Materials des Grundkörpers können die Funktionselemente fest in das Innere des Grundkörpers eingebettet werden. Dadurch sind die Elemente verliersicher und ortsfest in dem Grundkörper plaziert. Dadurch, dass die Funktionselemente direkt in den Grundkörper integriert sind, erleichtert sich die Montage der Rohranordnung. Des Weiteren stehen die Funktionselemente durch die Anordnung im Inneren der Rohranordnung direkt in Wirkverbindung mit dem Temperiermedium.In a method according to the invention for producing a pipe arrangement for the transport of temperature control medium according to a second embodiment, a preform made of polymeric material and at least one functional element to be arranged inside the pipe arrangement are provided, the at least one functional element being arranged inside the preform, the The preform with the at least one functional elements arranged therein is arranged in a blow mold and the tube arrangement is shaped by means of a blow molding process. Accordingly, the functional element is arranged in the base body before it is given its final shape in the blow molding process. Due to the plastic deformation of the material of the base body, the functional elements can be firmly embedded in the interior of the base body. As a result, the elements are placed in the base body in a captive and stationary manner. The fact that the functional elements are integrated directly into the base body makes the assembly of the pipe arrangement easier. Furthermore, due to the arrangement inside the pipe arrangement, the functional elements are directly in operative connection with the temperature control medium.
Es ist auch denkbar, dass ein erstes Funktionselement während des Blasformverfahrens direkt in den Grundkörper eingeformt wird, während ein zweites Funktionselement vor dem Ausformen im Inneren des Vorformlings angeordnet wird und seinen Platz nach Abschluss des Blasformverfahrens erhält. Insofern werden die beiden oben genannten Verfahren kombiniert. Dadurch ist es beispielsweise möglich, während des Blasformverfahrens ein Drosselventil in einem Kanal der Rohranordnung auszubilden und weitere Funktionselemente, wie Rückschlagventile, Sensoren, Pumpen oder Anschlussblöcke, in dem Grundkörper zu plazieren.It is also conceivable that a first functional element is molded directly into the base body during the blow molding process, while a second functional element is arranged in the interior of the preform before molding and is given its place after the blow molding process has been completed. In this respect, the two processes mentioned above are combined. This makes it possible, for example, to form a throttle valve in a channel of the pipe arrangement during the blow molding process and to place further functional elements such as check valves, sensors, pumps or connection blocks in the base body.
